How To Troubleshoot GE Fanuc IC697CPX772

Introduction: GE Fanuc IC697CPX772 Troubleshooting Guide

This is a troubleshooting guide for a 90-70 processor, part number IC697CPX772. Don’t be concerned about the revision letters, this test will be the same for all of them.

Step 1: Configure and Power Up

Go ahead and put the IC697CPX772 in the rack and power it up.
The first thing I want to do is plug in cable AS693232SNP, a programming cable, connected to the computer to Port 3. It has LED’s that flashes when it’s communicating. Go ahead and connect up.


 
Now it should be communicating and lights working as in the image above. If you are unable to connect then there’s obviously a problem with the processor. If you can’t get connected you won’t be able to follow this test. If this is the case, this is something we commonly work on or offer exchange programs and new units that can be shipped very quickly.

Step 2: Place Processor in Run Mode

The next thing you’re going to do is place the processor into run mode.
Go into your programming screen and clear any processor or I/O faults. Do NOT clear any other information from your processor that you may need such as flash memory, just I/O faults and processor faults. Go ahead and download and run. The processor is in an IC697CHS750 rack, the slots are empty because this test is just for the processor and it’s being powered by an IC697PWR711 power supply.
You should be able to see Port #3 talking and the LED light. As soon as this build is complete, you will be able to get it into run mode and you’ll have all three LED’s on for Ports 1, 2 & 3, this means that the processor is in fact in run mode.

The run mode is the middle LED the bottom is the I/O Inputs Outputs Enabled and you want to test this toggle switch below the LEDs that lets you shut off the I/O or put it back into run mode; make sure all of those work.

 
There is also a key on the top of the processor for memory protect, Turn that on and you should get an LED that comes on that tells you that your memory protect setting works.

Step 3: Test Port #2

Now, last two tests to do are to make sure all the ports work. So, unplug Port 3, plug into Port #2 and you should immediately have communication so you know it works. You can see on your software screen that it’s working. If so, unplug it and put back into Port 3.

Step 4: Test Port #1

Last is to test cable IC693CBL316 that fits to Port #1. It looks like a phone jack on one side and on the other side is a serial cable that plugs into your computer. As soon as you plug that in you should get some kid of response on the LED. You’ll see it blinking and talking so this is good all three ports work, all the switches work and the processor can go into run mode.

Step 5: Additional Steps if Necessary

If you still feel that the processor is a problem leave it running over night or over a weekend or for a couple days and what you want to do is make sure or check back that it’s still in run mode. If for any reason it kicks itself out of run mode there’s actually a problem with your processor you can go into your GE Proficy* Machine Edition and you can go into Target on your top menu bar into diagnostics and the diagnostics screen will tell you why it fell out of run mode.
